Judge: Jury will decide who screamed

Judge Debra Nelson ruled Saturday that testimony from the state's audio experts, Tom Owen and Alan Reich, will not be allowed in the George Zimmerman trial.

Zimmerman, a former neighborhood watch captain, is charged with second-degree murder for killing 17-year-old Trayvon Martin in Sanford, Florida, on the night of February 26, 2012. Zimmerman claims he shot the teenager in self-defense.

Nelson concluded that “there is no competent evidence that the scientific techniques used by Mr. Owen and Dr. Reich are generally accepted in the scientific field. There is no evidence to establish that their scientific techniques have been tested and found reliable.”

Nelson also confirmed that the order does not prevent the recordings from being played during the trial, and witnesses familiar with the voices of Zimmerman and Martin may still testify regarding the identity of the screams.
